MINIATURE CIRCUIT BREAKER SAMITE MOUNT, 2 POLES RATED AT 20A WITH BREAKING CAPACITY OF 3KA, C-CURVE.
Description
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit fromdamagecaused by excess current from an overload or short circuit.
Its basic function is to interrupt current flowafter afaultisdetected.
Circuit breakers are rated both by the normal current that they are expected to carry, and themaximumshort-circuit current that they can safely interrupt.
This latter figure is the ampere interrupting capacity (AIC) of thebreaker. It is in conformity with IEC 60947 standard.
Technical Data
Temperature Derating
The maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breakeris placed.
Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakersare installed.
